Hello Ankit, welcome to IBM-MAIN and mainframes... :-)
A long time ago at Uni one of the courses I took described how this all worked...and it used what is now z/OS to describe how it was done. Not that this can help you, just that it is such a basic idea that these days I don't think about it. As has been recommended you should review the ABC's of z/OS System Programming, but I think that the "Introduction to the New Mainframe" manuals may also be of help. The shape and size of the control blocks used by RSM and ASM in z/OS have changed over the years as the hardware and software have been modified to support the 24 bit, 31/32 bit and now 64 bit addressing schemes. The post by Sam Knutson recommended "TheThingKing" which is an excellent humorous description of how "virtual storage" works. As to Anton! ========= "because we are in America" Anton Britz 30 Aug 2007 10:09:50 -0500 As if! Many of the posters/lurkers on this list "are" NOT " in America". In fact in a later post you acknowledge that my mate Ron is Australian. Such bias as you have shown is not in the best interest of "world peace" (what every Miss World asks for :-D ) On Wed, 29 Aug 2007 15:02:57 -0500, Ankit <[EMAIL PROTECTED]> wrote: <snip> >Could anyone please explain : > >1.
